Hallo,
today we tried our application on an Win2008 Server with a Brother Scanner. At the System only a WIA-Driver is installed without any Twaindriver.

We used to select the scanner by the function SetSourceByStr. This work on all Systems without any problems when not only a WIA-Driver is installed.

It seems to me like a bug.

Now we use GetTwainSource and GetWiaSource to select the scanner.

Best Regards

Ralf

Hi Ralf

If you are passing only a source name to SetSourceByStr then it will fail with WIA in v6.3.2. You need to pass a raw device string, e.g.

My Cool Scanner||0||WIA||SCN

This is improved in v7.0.0

Hi Nigel,

thanks for the feedback.
I hadn't recognized, that i had to use for Wia the raw device str. I will test with the v7 if we can switch back to SetSourceByStr.

I'm looking forward for the v7.

Best Regards
Ralf
